Re: colloquium on Future of UTC
by Yann Droneaud Aug. 17, 2011

Aug. 17, 2011

Hi, Regarding this subject, the IERS is running a survey about UTC definition change. The survey was announced in the latest C bulletin (42) available at ftp://hpiers.obspm.fr/iers/bul/bulc/bulletinc.42 " IMPORTANT: After years of discussions, a proposal to fundamentally redefine UTC will come to a conclusive vote in January 2012 at the ITU-R in Geneva. This proposal would halt the intercalary adjustments known as leap seconds that maintain UTC as a form of Universal Time. The Earth Orientation Center of the IERS organizes a survey online with the objective to find out the strength of opinion for maintaining or changing the present system. Link to the questionnaire: http://hpiers.obspm.fr/eop-pc/index.php?index=questionnaire Your response is appreciated before 30 August 2011 " Regards. -- Yann Droneaud

Now that South Sudan is represented in the iso 3166 database it would be useful to add 'Africa/Juba' time zone. Kind regards, Paw

colloquium on Future of UTC
by Steve Allen Aug. 17, 2011

Aug. 17, 2011

On behalf of the co-chairs I announce a colloquium about the implications of possible changes to the definition of UTC which is scheduled for a vote by delegates to the Radiocommunication Assembly in January. The draft under consideration by the ITU-R would redefine the notions of time and calendar day in ways that would have broad side effects. The website for the colloquium is http://futureofutc.org/ Abstracts already received include contributions from national observatories, international agencies, geophysics and navigation communities. Software and operating systems remain underrepresented. I invite contributions from members of the time zone community and anyone who may have code, systems, or products which could be affected by changes in the definition of the radio broadcast time signals which underly them. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m

FW: Fingerprinting timezones

I'm forwarding this message from Conrad Irwin, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Conrad Irwin [mailto:conrad.irwin@gmail.com] Sent: Monday, August 08, 2011 7:59 To: tz(a)lecserver.nci.nih.gov Subject: Fingerprinting timezones Hello there, Thank you for the timezone database - it is a phenomenal resource. The problem I would like to solve is that of having to ask a user of a web-app for their timezone. While there is no way to directly query for the user's timezone, the javascript engine in their web-browser is capable of telling me the offset from UTC at any date. It seems like, by selecting some number of dates to query, I should be able to gather enough information to uniquely identify any given timezone (or at least make a very good guess for a large proportion of the user-base). Before I embarked on doing this, I wanted to ask if anyone has seen a similar attempt in the past? Are there some "gotchas" that mean that this isn't actually as feasible as I naïvely hope? Conrad

I'm forwarding this message from Michael Pelley, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. Once we learn that the proclamation has been issued, the changes should up at ftp://elsie.nci.nih.gov/pub about two weeks later. >From there propagation depends on database users. --ado From: Pelley, Michael [mailto:MPelley@gov.nl.ca] Sent: Friday, August 05, 2011 12:43 To: tz(a)lecserver.nci.nih.gov Subject: Pending changes to time of Newfoundland Time Zone for Daylight Savings Time Folks, The Government of Newfoundland and Labrador has pending changes to modify the hour for daylight savings time to come into effect in November 2011. This modification would change the time from 12:01AM to 2:00AM on the dates of the switches of Daylight Savings Time to/from Standard Time. As a matter of reference, in Canada provinces have the authority of setting time zone information. The legislation has passed our legislative body (“The House of Assembly”) and is awaiting the proclamation to come into effect. You may find this information at: http://www.assembly.nl.ca/legislation/sr/lists/Proclamation.htm and search within that web page for “Standard Time (Amendment) Act”. The Act may be found at: http://www.assembly.nl.ca/business/bills/Bill1106.htm We would appreciate if we could receive some guidance as to: • The official mechanism for implementing this change; • The timeframe for the implementation of the change within the TZ sources. Thank you.
